IMPROVEMENT IN BUCK-SAWS.

The Schedule retn-ed to in these Letters Patent and making part of thelame.

.L ARIEL B. SPROT, of Mnncy, in the county of' Lycoming :ind Stute ofPennsylvania, have invented certain Improvements in Buck-Saws. l v

My invention yeonsistsin strztiningnnd bracing zt saw und frame by meansof' n. lever and bar so pivoted together thnt, when the end of the'leveris elevated, it will shorten the space between one en d'of the lever undone end of the bnr, nnd when depressed it will lengthen the space andthree-the tranne ftpnrt, so ns to strain the saw und ironie; then byfasteningthe end of the lever it will brace tite frame :md sew.

The accompanying drawing n. side elevation of' a;

-A A represent thttport ofthetrtnne composed ofl wood, und mznle in theusuztl way ot.' nntking buck- ;ztws, with holes nt g g s s.

'lhe ends of the wooden pieces A A at r/ gnre ripped down with at sow,so as to receive the stretcher C, and with apertures made in the inwardside ait 1P F. .v

v B is the sztwj, with holes in the ends to correspond with holes in thewooden ports A A.

O is n stretcher, tnznle ot' :t piece of tint iron, inwpttrts of thetranne nt g' g', it-ntl also holes i i ii in the wide end to receive thepin h at the end of'the leier D.

D is n'lever, one cndof which is inserted in the aperture at' F, undt-he other. cnd with :t pin, h, vlonde to tit the holes i t', i inetnthe end of tite stretcher, which lever is riveted to the bnr E ntG.'

'lhe lxtrsD'tid E tray be made of what iscommonly celled angle-iron, orsteel, to make them iighter. l

The bnr E is riveted tothe lever'D atene earl, and.

the other end is inserted in the aperture F2; :ind that pzn't of thelever D between F and G, and the bttr E,

when depressedby means ot' tite lever D, strain the sew, ond when thepin h is inserted in either of thel holes i i 4i i the sow and frame isbraced and held,

Hoving thus described the dierent parts of a. snw

and frznne with my improvemengl will new proceed -to describe thetnnnner in which I strninand bruce the same.

After t-lie stretcher C and the saw B are fastened in the wood,-bytnt-'ans of screws orfpns as seen :it g' g' s s', I take the bttrs D:tod E, riveted together :.t G, and insert one end oi' eac-lr into theapertures nt F :unl F2, with the cnil ot' the lever with pin lh at k.

I.then press the lever D down/ward nntl the sow is snllicientlystruined, zn|d then slip the. pin h into one ot' the holes 'i i i iopposite the pin, :md the sew is then strained und braced. Han-ing thnsdescribed my invention :nid the manner of working the sinne,

What I elnim as of my invention is The combination of the leves D withthe bnr E and stretcher O, for the purpose set forth and described.
